Course
The Trask River is formed by the confluence of North Fork Trask River and South Fork Trask River near Trask County Park in the Tillamook State Forest. It is paralleled for much of its length by Trask River Road. Flowing generally west, the river receives Rowe Creek from the left about 16 miles (26 km) from the mouth, then Samson Creek from the right about 1 mile (1.6 km) later. Over the next 4 miles (6.4 km) Burton, Blue Ridge, Hatchery, Trowbridge, Little Rock, and Panther creeks all enter from the right. The river passes a United States Geological Survey stream gauge at river mile (RM) 10.95 or river kilometer (RK) 17.62, just before receiving Cedar Creek from the right.
Thereafter, Gold and Hanenkrat creeks enter from the left and Green Creek from the right. The river receives Mill Creek from the left about 5 miles (8.0 km) from the mouth. About 1 mile (1.6 km) later, the stream passes under U.S. Route 101 and flows around the southwestern edge of Tillamook. Receiving Hoquarten and Nolan sloughs from the right, it merges with the Tillamook River and flows into Tillamook Bay near Memaloose Point.
